liquid; means connecting a source of equal pressure with the delivery conduit near the upper end thereof; and means to control this connection.

A feature of my invention consists in having the pressure conduit above referred to of relatively small capacity so as to regulate and control the movement of the liquid in the delivery conduit and prevent undue disturbance of the liquid while being returned to the package.

Another feature of my invention consists in providing means to exhaust the delivery conduit in a regulated fashion when the liquid is first being elevated therein so as to prevent undue or undesirable disturbance of the liquid at this time.

An important feature of my invention is the means for controlling the flow of liquid which means also controls the application of pressure to return the liquid to the source.

Other features are described below:

In the drawings: Figure 1 is a diagram showing an apparatus embodying my invention. Fig. 2 is an elevation partly in section of the improved faucet hereinafter described for use in that form of-my inven tion shown in Fig. 1. Fig. 3 is a section on line 38 of Fig. 2. Fig. A is a section on line 44 of Fig 2. Fig. 5 is a section on line 55 of Fig. 2. Figs. 6 and 7 are details hereinafter described.

A is a tank holding compressed air or the like and constituting a source of pressure which is connected by a conduit a with a vessel A for the liquid and this receptacle may be the usual keg or package. Leading from vessel A is a delivery conduit a connected with a faucet A which is threaded to receive a nut a by which the faucet is clamped to the bar fixture or the like X.

Mounted on faucet A is a sleeve A which has a double branch pipe a and passages or leading therefrom to packing boxes a A plate A alongside sleeve A is provided,

having bosses a through which extend holes (H. A plate B at the opposite side of fixture X has a boss Z) with a hole 5 through it to receive a pipe B which connects a passage 6 with one of the branches o leakage at the oints between 6 and pipe B and branch a and pipe B being prevented by packing b Passage 6 leads through casing D to a valve chamber (Z and is part of the pres sure conduit hereinafter referred to. A port (Z leads from one end of easing D to the opposite end and is part of the delivery conduit a hereinafter referred to.

Upon the top of the casing is a segmental lug (F. The hollow plug E within the chamber cl has ears 6 and ports 6 for registry with the liquid conduit d and these ports are of the same size as port d. Plug .E has also ports 6 at right angles to ports 6 and also for registry with conduit (1. Port 6 is for registry with pressure conduit 79 At its lower end plug E receives washer e and is threaded toreceive nut 6*. Plug F within plug E has a handle f, an ear f to cooperate with ears 6; a port f to register with ports 6; a port f opening at one end into port f and adapted at its other end to register with port 6 A port f communicates at one end wit-h port f and at its other end is adapted to register with that part of port cl at the outlet end; also plug F is threaded at f to receive a cap F and nut F In the normal position of rest of my apparatus port 6 of hollow plug E registers with passage 6 and port f of plug F registers with port 6 of plug E.

In starting my apparatus the handle is turned until ear f bears upon ear 6 in which position the pressure in passage 12 will be shut off from communication with conduit cl and the air in conduit d will pass out through the plugs E and F by means of the ports 6 and f into the atmosphere owing to the pressure upon the liquid in receptacle A. The handle is then turned a quarter turn farther until ear 6 bears against segmental projection d plug F having been thus turned a half revolution and plug E a quarter from the original position. In this position the ports 6 register with conduit d through the casing but the flow of liquid is I ports is illustrated in Figs. 2, 3, 4 and 5 of the drawing. liquid the handle is turned back a quarter turn when the liquid will flow smoothly and without disturbance through the continuous round passage afforded by the conduit d and ports 0 and f To shut ofi the fluid the handle is turned back to the position shown in Figs. 2 and 4:. hen it becomes desirable to shut down the apparatus for any considerable time as in the case of closing down for the night the handle is turned a half turn to its first position when port 6 of the casing registers with port 0 of plug E and f of plug F and then the pressure coming through sleeve A and pressure pipe 9 and being the same pressure that is exerted on the liquid at its source of supply, the liquid will return to its source of supply, under the influence of gravity and without any disturbance owing to the equalizing of pressure and the relatively small capacity of port and 6 It will therefore be clear that with my apparatus there can be no waste of the liquid due to deterioration on account of standing in the pipes or other cause, and that the first portion of liquid drawn off when the apparatus is used will be in as good condition as any drawn later, and that the normal coir dition of liquid is not disturbed at the starting or stopping of the apparatus or at any time and this is due to my equalizing and control of the pressure and to the novel construction of the faucet. The purpose of having a double branch a and double nipple a in sleeve A is to allow for adjustment. That is in some cases it is necessary to install my apparatus with the sleeve A in inverted position from that shown in Fig. 2 in which case the other opening a connects with pipe B which brings the nipples a upon the under side of the faucet. It will be understood that the branch of the pipe a and the opening 0. which are not in use are closed by screw caps or the like.

The function of ears 6 in addition to being a means of turning plug E is that they act as stops in the turning of the handle so that the operator can readily tell when the handle is in the exact position for passage of the fluid and for completely shutting off the fluid and when it is in the exact position for equalizing the pressure and thereby return the liquid to the receptacle, it being clear that the means for controlling the flow of liquid controls also the equalizing of the pressure. By the use of washer e and nut e I can make the turning of plug E much harder than the turning of plug F with its cap F and nut F and in this way the operator can readily tell when he is moving merely plug F and when he is moving plug E in addition to plug F. It will be clear that in my apparatus I insure a passage of In order to allow the flow of liquid through a uniform round passage free from obstructions or constrictions which is highly desirable, and that my arrangement of plugs, which is the preferred form of my invention, provides a very simple and efficient arrangement for controlling the flow of liquid and for returning the liquid to the source of supply.

A very desirable feature of my apparatus consists in making the exhaust of relatively smaller size than the delivery conduit for the purpose of insuring at the time the apparatus is started a delivery without stirring up the liquid.
